Final answer:
The statement that the metal in binary compounds takes on an -ide ending is false. Metals retain their original names, and the -ide suffix is added to the nonmetal component.
Step-by-step explanation:
In binary compounds, the metal, which is the positively charged cation, retains its elemental name. You do not add an -ide ending to the name of the metal. Therefore, the statement that in binary compounds, the metal keeps its original name or takes on an -ide ending is false.
When naming binary ionic compounds with metals that form only one type of cation, the process is straightforward. You name the metal cation first, followed by the nonmetal anion with the suffix -ide. In cases where metals have multiple oxidation states, such as transition metals, a Roman numeral indicating the charge is used in parentheses after the metal's name. An example is iron(III) chloride.
